1970年 Theo Botschuiver & Jeffrey Shaw []
Balloon of metal
The liquefied LPG, it can store in the spherical tank.
In the case of 20 ℃, the pressure required to liquefy the propane is 0.86MPa.
The inside of the fuselage structure of the jumbo jet has been made in setting a positive pressure.
The jumbo jet flying a low altitude of the atmospheric pressure is pressurized to 0.8 atm. It becomes the balloon state by the pressure difference created between the cabin and the outside.
If the cabin upon landing remains at 0.8 atm, it became a negative pressure against the atmospheric pressure. And trouble will occur in the strength maintenance.
1985「 Pressure bulkhead corruption」JAL123 Ostakayama
Reinforced glass cloth and teflon membrane by iron wire.
1979「Metrodome」
Iron wire are dispersed large tension internal air pressure will occur. 340 tons of roof, is supported by internal air pressure 20mmAq.
Air pressure 20mmAq is the same pressure as the water pressure at the water surface under 2cm.
At the time of snow, it is necessary to addition to air pressure commensurate with the weight of the snow.

Control of dirigible
1901「Santos-Dumont #5」Santos-Dumont
Santos succeeded in the flight that goes around the Eiffel Tower.Changing the size of the air chamber located inside of the hydrogen gas chamber adjust the buoyancy of the airship by.
This method of buoyancy adjustment is the same principle as the fish. Also has been used to the flying of the submarine.

air suspension
Air springs can attenuate the fine vibration. It can not be absorbed by the metal spring.
Since there is not sliding parts, there is no need for maintenance.
By varying the amount of air, it is possible to set the spring rate and ride height.

Human body and balloons
 
   
Soft culture
As a material for symbolic and eternal monument of authority, stone and metal have been the mainstream of art.
On the contrary, soft materials such as fur, straw, cloth, bamboo, gourd-mud, it has been considered to have a low value.
However, human body likes warm and soft things than hard and cold things.
Automotive interior representing the machine civilization has been covered with a soft cushion.

For the pressure difference between the inside and outside of the space suit, it need a large force when bending the joint portion.
Therefore, early spacesuit lowers the internal pressure to 0.3 atm, was filled with pure oxygen。Extravehicular activity
